Death's Other Dominion

Lore & Background

The episode opens on a frozen planet where two humans, Dr Cabot Rowland and Colonel Jack Tanner, observe the approach of Earth's Moon. They invite Moonbase Alpha to visit, but Tanner warns against it. Commander Koenig leads a crew down, but they are separated in a blizzard. The Thulians, survivors of a 1986 expedition to Uranus, have been stranded for centuries without aging. Rowland believes he can isolate the immortality factor and is building a spacecraft called Phoenix. Tanner shows Koenig the failed experiments—mindless, zombie-like "Revered Ones." Koenig disrupts Rowland's work, but faces backlash from Dr Russell and Professor Bergman. Rowland dies shortly after leaving Thule, his body rotting to match his true age. The Alphans decide not to settle on Thule, and the Thulians agree to abandon the Phoenix project to care for the Revered Ones.

Reader's Guide

The episode is noted for its Shakespearean influences, with guest characters quoting King Lear and displaying traits of Shakespearean fools and rulers. Critics have praised the performances of Brian Blessed (Rowland) and John Shrapnel (Tanner), as well as the twist ending. The plot was loosely based on the 1933 novel Lost Horizon. The title comes from a verse in Romans 6. Production faced challenges from formaldehyde fumes used to create fake ice, which caused breathing difficulties and required additional pumps. The Phoenix miniature was modeled on the ark from the 1951 film When Worlds Collide. The episode received mostly positive reviews, with some critics calling it a serious adult drama and a high point for the series, though others found it sluggish or hokey. It is considered a strong exploration of immortality and the consequences of technological arrogance.

Did You Know?

• The episode's title was inspired by a verse in Romans 6:9: 'death hath no more dominion over him'.
• Fake ice was created by spraying sets with a plastic-based spray called 'Snow-Cel' or similar, not formaldehyde.
• The Phoenix filming miniature was modelled on the ark spacecraft from the 1951 film When Worlds Collide.
• One effects shot of the Thulian surface was recycled for the Series 2 episode 'One Moment of Humanity'.

The Frozen Paradox of Ultima Thule

The narrative centers on a haunting encounter between the Alphans and humans stranded on a frigid world they call Ultima Thule. These survivors, originally part of a 1986 Uranus expedition, were flung beyond the Solar System by a space warp and have endured centuries of isolation without aging. Dr Cabot Rowland, convinced he can isolate the mechanism behind their agelessness, regards the Thulians as near-deities and is building a vessel called Phoenix to carry them into the cosmos. Colonel Jack Tanner, by contrast, urges the Alphans to stay away and exposes the grim cost of Rowland's ambitions: the Revered Ones, former expedition members reduced to mindless husks by failed experiments. After a blizzard scatters Koenig's landing party and the Thulians shelter the unconscious survivors underground, Freda Tanner orchestrates a revolt that destroys Rowland's laboratory. The climax arrives when Rowland departs Thule aboard the Eagle and instantly catches up with his true biological age, collapsing into a decayed corpse. Koenig is left pondering whether mortality lends existence its meaning, while Tanner and his people resolve to abandon the Phoenix project and devote themselves to restoring the Revered Ones.

Behind the Frozen Sets

Principal photography took place at Pinewood Studios in September 1974, with the Terpiloff-Barrows script completed in late August. The regular cast began shooting on 9 September, and the guest ensemble joined two days later. By the 18th, the schedule was running roughly a day behind, and the wrap on 23 September proved busier than anticipated. One of the most notable production challenges involved creating the illusion of ice on the Thule sets: the crew sprayed formaldehyde across the surfaces, and the resulting fumes caused breathing difficulties and streaming eyes among cast and crew. Air-purification pumps were deployed to address the issue, and an environmental health officer along with a private doctor certified the set as safe. Guest actors Blessed and Shrapnel were content to continue, but the Landaus' American agents demanded additional purification equipment and firm assurances of no lasting harm before clearing their clients to resume. The Phoenix spacecraft miniature, crafted by Martin Bower, drew its design from the ark in the 1951 film When Worlds Collide. Post-production wrapped on 27 November 1974.

Shakespeare, Keats, and the Shadow of Lost Horizon

The episode's creative DNA is deeply literary. Its plot was loosely adapted from the 1933 fantasy adventure novel Lost Horizon, which had seen a second film adaptation released in 1973. The title itself borrows from the biblical book of Romans, chapter six: 'death hath no more dominion over him,' a verse concerning the resurrection of Christ. The script's character notes for Colonel Jack Tanner described him as possessing 'the manner of a Shakespearean fool in search of an audience,' and his dialogue weaves in lines drawn from King Lear alongside references to works by John Keats and Gilbert and Sullivan. Critics who reviewed the finished broadcast specifically flagged these Shakespearean echoes in the guest characters' speech as a standout element. The production also made practical adjustments from the written script: the Alphans were originally described as wearing spacesuits on the Thule surface, but the finished episode has them in ski salopettes, jackets, and goggles. The script's cold opening likewise included additional footage set on Alpha beyond what appears in the transmitted version.

Broadcast, Reception, and Place in the Series

Produced as the fourteenth episode in the production sequence but positioned as the thirteenth in the first series, 'Death's Other Dominion' was written by the husband-and-wife team of Anthony Terpiloff and Elizabeth Barrows and directed by Charles Crichton under the Group Three banner for ITC Entertainment. The episode first reached viewers in Australia on 11 August 1975, with the United Kingdom following on 2 October of the same year. Critical response was largely favorable, with reviewers singling out the Shakespearean inflections in the guest characters' dialogue as a particular highlight. The show's premise of Moonbase Alpha's crew navigating a rogue Moon through interstellar space after a nuclear detonation ejects it from Earth's orbit frames the episode's central question: what happens when a group of people discovers they can no longer die? The Thulians' centuries of frozen existence, their failed experiments, and their eventual decision to set aside the Phoenix project in favor of caring for the Revered Ones lend the story a distinctly melancholic resolution. Koenig's closing musing on whether death is what gives life true meaning lingers as the Moon departs the Thulian system.
